Comment (by Ilya87):

 Part 2 of this bug:
 https://mega.nz/#F!61VEFQwB!wUEggqchsrYqDDgogCb2Ng

 ffmpeg -i klk.mkv -i klk_reference.mkv -lavfi
 libvmaf="model_path=/usr/share/model/vmaf_v0.6.1.pkl:pool=mean:log_path=vmaf.log"
 -f null -

 VMAF score nan, 0 score for frames also appears. klk16.mkv - yuv420p10le,
 klk16_reference.mkv - yuv420p.

 2 files are absolutely valid matroska files.
